How to Install LM Studio on DGX Spark Ubuntu ARM64 | GUI + Headless Server Setup

Description
In this video, I walk step by step through how to install LM Studio on Ubuntu ARM64 and how to set up the headless LM Studio daemon / LLM server on an NVIDIA DGX Spark. Installing LM Studio on Windows is simple, but on Linux and ARM64 hardware the process is much more manual. I show both approaches: the GUI desktop installation for workstation use and the headless setup for running your DGX Spark as a dedicated local LLM server.

Then I switch to the headless route and demonstrate how to install the LM Studio daemon, use the LMS command line, download and run models, expose the API on port 1234, and configure a systemd user service so the server starts automatically even without a logged-in session. I also cover practical differences between Windows and Linux, unified memory behavior on the DGX Spark, CUDA detection, remote model access through LM Studio remote, and how to update the daemon cleanly when new versions are released. If you want to run local LLMs on Ubuntu, ARM64, or NVIDIA DGX Spark, this tutorial will save you time and help you avoid the small issues that usually appear during installation. What you’ll learn: LM Studio install on Ubuntu ARM64 DGX Spark local LLM setup LM Studio GUI vs headless daemon AppImage extraction and permissions Chrome sandbox fix Desktop icon and autostart on Ubuntu LMS command-line usage systemd service configuration API server on port 12341234 Remote access to local models Upgrade LM Studio If this video helps, please like, subscribe, and leave a comment with your DGX Spark or Ubun
